ANSWERS TO APPLIED PROBLEMS
24. Suppose you have just inherited $10,000 and are considering the following options for

Option 1: Put the money in an interest-bearing checking account that earns 2%. The FDIC
insures the account against bank failure.
Option 4: Hold the money in cash and earn zero return.
a. If you are risk-neutral (i.e., neither seek out nor shy away from risk), which of the four
options should you choose to maximize your expected return? (Hint: To calculate the
expected return of an outcome, multiply the probability that an event will occur by the
outcome of that event.)
b. Suppose Option 3 and Option 4 are your only choices. If you could pay your friend $100
to find out extra information about Mike that would indicate with certainty whether he
will leave town without paying, would you pay the $100? What does this say about the
value of better information regarding risk?
a. With Option 1, since deposits are insured it can be assumed a riskless investment.
Thus, the expected total payoff would be $10,000 × 1.02 = $10,200. With Option 2, a
b. Option 3 implies the very real possibility of either receiving nothing (if he actually
leaves town), or $10,800 (if he indeed pays as promised). If you don’t pay Mike, you
